Field
[0001] The present invention is concerned with leads (also known as leashes) for domestic
animals such as pets, particularly for dogs, and in particular for leads where the
lead is disengageable from a harness or collar on the animal. In particular, it is
concerned with a lead that can be rapidly attached in order to bring a domestic animal
rapidly under control, and also rapidly and easily released to allow the animal to
be unleashed.
Background to the invention
[0002] Lead structures, collars, harnesses and the like are available in various designs
intended to control domesticated animals. A common arrangement, particularly for use
with dogs, is the use of a collar fastened around the neck of an animal, with the
collar attached to a lead. The person controlling the animal grasps a handle at the
proximal end of the lead and the distal end of the lead is attached to the collar.
[0003] With such a collar arrangement, it is desirable that the lead is easily attachable
to the collar and can be removed, for instance, to allow the animal to roam freely.
[0004] Domestic animals, such as dogs, may need to be brought under control rapidly depending
upon the prevailing circumstances. In such a situation, to protect the safety of the
dog or the safety of others, it may be necessary to rapidly attach a lead to a dog
already wearing a collar, or it may be necessary to attach a collar to the dog rapidly
so that a lead can subsequently be attached to bring the dog under control.
[0005] Typical prior art collars, particularly dog collars, have used conventional buckle
and strap arrangements, with a pin-buckle adjustable on a strap with poles through
which the pin passes. Other known arrangements use, for instance, Velcro™ straps in
order to provide adjustment of the collar. Another known arrangement uses a toothed
belt and ratchet combination where the collar is fastened by inserting the distal
end of a toothed belt into a slider having a ratchet, and the belt is tightened by
pushing the toothed belt into the slider with the ratchet grasping the toothed belt.
The usual manner for attachment of a lead to a collar is the use of a fastening loop,
enclosed by a rim, attached to the collar interlocked with a hooked clip provided
at the distal end of the lead. To attach the lead to the collar, the hooked clip is
engaged with the fastening loop by hooking the loop so that the loop enters an aperture
defined by the hooked clip through an opening. The opening is then closed, by some
gate means, to prevent the fastening loop inadvertently disengaging from the hooked
clip. The fastening loop may have a rim of flexible plastic or cord attached to a
collar or harness, but is typically a metal ring or D-ring, with the ring forming
the rim of the loop, attached to a collar or harness.
[0006] By "hooked clip" is meant an attachment means in the form of an arcuate body enclosing
an opening or aperture with a gap in the arcuate body through which a fastening loop
can pass so that the fastening loop may interlock with the arcuate body. The gap will
be between opposed terminals of the arcuate body, at least one of which is positioned
to provide a hook shape to facilitate interengagement of the arcuate body and the
rim of the fastening loop. The gap is typically closable by a sprung gate, which may
by pushed open by the rim of the fastening loop to permit entry of the fastening loop
through the gap as the hook is clipped onto the loop. In another embodiment, a screw
fastener may be used to close the gap once the fastening loop and arcuate body are
interengaged.
[0007] Typical hooked clips used for animal leads include spring clips such as karabiner
arrangements which have a sprung side arm or gate which closes the hook aperture after
the hooked clip has been attached to the collar. Maillon type arrangements or shackles
may also be used where the clip is openable by means of a screw arrangement or, for
instance, slide clips where a section of the clip is slidably removable to allow a
gap to be formed through which a D-ring can pass in order to engage with a clip. All
of these arrangements require some degree of manipulation when disengaging hooked
clip from the fastening loop on the collar, and this may be difficult to achieve when
the lead is held under tension, for instance by an animal straining on the lead. See
e.g. document
WO-A-2006/076769.
[0008] A problem with prior art arrangements as set out above is that in order to release
the animal from the lead, manipulation of the hooked clip is necessary in order to
disengage the hooked clip from the fastening loop in order to open any gate arrangement
and to detach the fastening loop from within the aperture of the hooked clip so that
the animal is released or unleashed. This may be particularly difficult to achieve
when the animal is struggling or when the animal is straining to be unleashed, so
that the lead, fastening loop and hooked clip are held under tension, so that the
hooked clip will have to be urged against the tension of the straining animal in order
to remove or disengage the rim of the fastening loop from the hooked clip, possibly
whilst also holding open the gate arrangement of the hooked clip to permit the fastening
loop to be disengaged. This may be of particular importance for leads for working
animals such as flock-control dogs, guard dogs and police dogs, where the dog may
be straining to be released to do its job, and where the delay resulting from the
manipulation required to permit release could be inconvenient or dangerous. For instance,
delay in releasing a guard dog or a police dog could give time for an assailant to
assault the dog handler.
[0009] Hence, there is a need for a collar arrangement and for collar and lead assemblies
which overcome or address at least some of the problems set out above.
Summary of the invention
[0010] One object of the invention, amongst others, is to provide a lead for an animal which
is adapted to permit easy and rapid attachment of a lead to a collar or harness, so
that the animal can be brought under control rapidly, and where the lead is readily
and rapidly detachable from the collar or harness by a handler, even when the animal
is straining against the lead so that the lead is under tension. It is also desirable
for inadvertent release of the animal from the lead to be avoided.
[0011] Hence, the invention provides an animal lead comprising an elongate flexible member
arranged for gripping by a handler at a proximal end, and comprising an attachment
means for releasable attachment to a collar or harness at a distal end,
wherein the attachment means comprises:
a hooked body defining an aperture partially enclosed by the hooked body, the aperture
having a gap between first and second terminals of the hooked body closable by a gate,
and
a release frame to which the gate is operably mounted,
the release frame mounted to the hooked body for relative movement thereto and having
an open configuration in which the gate is retracted from the gap with the release
frame to leave the gap open and a closed configuration in which the gate is held in
a first position, by the release frame, to close the gap with a proximal end of the
gate at the first terminal of the hooked body and a distal end of the gate at the
second terminal of the hooked body, wherein the attachment means comprises a retaining
means for holding the release frame in the closed configuration, and
wherein the gate is urgeable, relative to the release frame, when held in its closed
configuration, towards a second position, wherein in the second position, the distal
end of the gate is positioned away from the second terminal of the arcuate member
and into the aperture towards the hooked body whereby the second terminal of the hooked
body may be clipped into a fastening loop of a collar or harness and whereby the hooked
body is retainable in said fastening loop by the gate being released to its first
position to close the gap,
the release frame further comprising a decoupling member arranged to sweep across
the aperture as the release frame is moved from the closed to the open configuration,
whereby the decoupling member urges said fastening loop to disengage from the aperture
by sweeping a rim of said fastening loop out of the aperture past the second terminal
through the gap.

a dog, by means of a lead according to the first aspect of the invention.
[0013] Also disclosed herein is the use of a lead according to the first aspect of the invention
for holding and releasing an animal, such as a dog.

also be taken to include the meaning "consists essentially of" or "consisting essentially
of.
[0015] The optional and/or preferred features set out may be used either individually or
in combination with each other where appropriate and particularly in the combinations
as set out in the accompanying claims. The optional and/or preferred features for
each aspect of the invention set out above are also applicable to any other aspects
of the invention, where appropriate.
[0016] The invention provides an animal lead comprising an elongate flexible member arranged
for gripping by a handler at a proximal end, and comprising an attachment means for
releasable attachment to a collar or harness at a distal end.
[0017] The elongate flexible member may be of any suitable material such as textile, polymer
(e.g. nylon, Kevlar™, natural or synthetic rubber, neoprene, etc.), leather or the
like. It may be in the form of a strap or a rope or cord. The strap or cord may be
reinforced with fibres such as carbon fibre or may include metal reinforcement or
the like.
[0018] At the proximal end, the lead may be provided with a handle in order to assist gripping
by a handler, for instance the elongate flexible member may be formed into a loop
at the proximal end for gripping by a handler. In another embodiment, a retracting
handle may be provided, having a mechanism whereby the elongate flexible member may
be retracted or paid out at the discretion of the handler. Such handles for varying
the length of a lead are well known in the art.
[0019] The attachment means comprises a hooked body defining an aperture partially enclosed
by the hooked body, the aperture being entered through a gap between first and second
terminals of the hooked body. The aperture is closable by a gate arrangeable to extend
between the first and second terminals to close the gap. In use, the hooked body will
have its second terminal hooked into a fastening loop, such as a ring or D-ring of
a collar or harness, so that the loop passes through the aperture, interlocking with
the hooked body and held within the aperture of the hooked body by the gate across
the gap between the first and second terminals.
[0020] The attachment means also has a release frame to which the gate is operably mounted.
[0021] The release frame is mounted to the hooked body for relative movement relative to
the hooked body. As the release frame is moved relative to the hooked body, the gate,
attached to the release frame, will move with it. The release frame is moveable between
an open configuration and a closed configuration. In the open configuration, the gate,
moving with the release frame to which it is operably attached, is retracted from
the gap to leave the gap open. The attachment means comprises a retaining means, such
as a sprung latch or biasing means, for holding the release frame in the closed configuration.
In the closed configuration, the gate is held in a first position, by the release
frame, to close the gap with a proximal end of the gate at the first terminal of the
hooked body and a distal end of the gate at the second terminal of the hooked body.
However, the gate is also moveable or urgeable relative to the release frame, and
may be urged from this first position, closing the gap, towards a second position,
wherein in the second position, the distal end of the gate is positioned away from
the second terminal of the hooked body, and into the aperture towards the hooked body.
This allows the second terminal of the hooked body to be clipped into a fastening
loop of a collar or harness. The hooked body is holdable within the fastening loop
by the gate being released to its first position to close the gap across the terminals.
[0022] The release frame further comprises a decoupling member arranged to sweep across
the aperture as the release frame is moved from its closed to its open configuration,
whereby the decoupling member urges the fastening loop to disengage from the hooked
body by sweeping the rim of the fastening loop of the collar or harness out of the
aperture, past the second terminal and through the gap. The decoupling member will
typically be a curved arm forming part of the release frame and arranged to have its
distal end at the second terminal when the release frame is in the open configuration.
[0023] Suitably, the gate is pivotally mounted to the release frame at its proximal end
to be pivotable between the first and second positions, with the gate biased towards
the first position by a biasing means. Typically, the gate will be mounted on an axle
on the release frame, with a biasing means such as a spring urging the gate towards
the first position. A camming means or a stop on the gate and/or release frame may
hold the gate in the first position and allow it to be moved, against the force applied
by the biasing means, towards the second position. When the release frame is in the
closed configuration, the urging of the gate may be achieved by pushing or clipping
the distal end of the gate against a rim of a fastening loop, such as a rigid ring
or D-ring of a collar or harness, so that the gate opens inwards towards the aperture
sufficiently to allow the rim of the fastening loop to slip into the aperture of the
hooked body through the gap, past the gate and second terminal of the hooked body,
to be interlocked with the hooked body and held within the aperture. Once the ring
is inside the aperture, the gate, now urged back to the first position by the biasing
means to close the gap, prevents egress of the rim of the fastening loop through the
gap past the gate.
[0024] The retaining means for the release frame may be a clip or latch arrangement to hold
the release frame in the closed configuration relative to the hooked body. For instance,
a sprung latch may be used as retaining means. In one embodiment, the release frame
is suitably pivotably mounted to the hooked body to be pivotable between the open
configuration and the closed configuration and the holding means is a second biasing
means arranged to bias the release frame towards the closed configuration. Typically,
the release frame will be mounted to pivot about an axle affixed to the hooked body
towards the distal end of the hooked body.
[0025] Typically, the release frame and gate will be arranged to pivot in the same plane,
so in other words, the axles about which they are arranged to pivot will have substantially
parallel axes. These axes will be typically substantially normal to a plane formed
by the hook of the hooked body. Preferably, the hooked body will be hollow whereby
the release frame, in its closed configuration, is substantially concealed within
the interior of the hooked body.
[0026] The attachment means may comprise a releasable locking arrangement having a locked
configuration in which the release frame is held in the closed configuration and an
unlocked configuration in which the release frame is movable between the closed and
open configurations. Any suitable locking arrangement may be employed, such as a latch
means, a locking pin or the like. In other words, the release frame may be lockable
in the closed configuration so that it has a locked configuration in which the release
frame cannot move relative to the hooked body. The releasable locking arrangement
may also be the retaining means for the release frame, but preferably, the retaining
means and locking arrangement are separate. Even in this locked configuration, it
may still be possible to release the hooked body from a fastening loop, but it would
be necessary to manipulate the gate manually from the first to the second configuration
and to unhook the second terminal of the hooked body from the fastening loop. In the
locked configuration, the release frame cannot be moved to its open configuration
and so any disengagement must be by manipulation of the gate in the manner known for
prior art hooked clips. However, whilst in this locked configuration, the hooked body
may still be easily clipped onto a fastening loop by pressing the rim of the fastening
loop against the gate to urge the gate open sufficiently to permit the fastening loop
rim to pass into the aperture to interlock with the hooked body, the gate closing
behind it to hold the fastening loop in place.
[0027] A suitable locking arrangement may comprise a locking pin arranged to pass through
openings in the release frame and hooked body, in the locked configuration, to hold
the release frame locked in the closed configuration. The locking pin is removable
to provide the unlocked configuration. The locking pin may be shaped to hold the pin
in place within the openings until the pin is subjected to a sufficient withdrawal
force for disengagement. For instance, the pin may be a split pin: such split pins
are well known. The pin may have a head arranged for gripping to assist in its withdrawal
by a handler, and may be provided with a lanyard to attach it to the lead in order
to avoid inadvertent loss.
[0028] The lead may further comprise a first actuating means arranged to move the release
frame from the closed to the open configuration when actuated. In a simple arrangement,
the release frame may have a handle, ring or loop which the handler grasps and pulls
to move the release frame from its closed to its open configuration in order to effect
the rapid disengagement of the hooked body from a fastening loop of a collar or harness.
[0029] However, a remotely operable first actuating means (for instance actuated from the
proximal end of the lead) may be used in order to avoid the need for the handler to
directly manipulate the attachment means near the head of an animal (hence reducing
risk of biting of the handler by the animal). Hence, the first actuating means may
comprise a lanyard operably connected to the release frame at the distal end of the
lead and to a first trigger at the proximal end of the lead, whereby pulling the trigger
moves the release frame from its closed to its open configuration, enabling remote
unleashing of the animal even with the lead under tension (provided that any locking
arrangement has first been arranged into its unlocked configuration). In other words,
the lead may comprise a first actuating means arranged to move the release frame from
its closed to its open configuration by means of a first trigger located at the proximal
end of the lead. Similarly, the locking arrangement may be provided with a second
actuating means operable to disengage the locking arrangement into its unlocked configuration
by means of a second trigger located at the proximal end of the lead. In other words,
the second actuating means unlocks the attachment means and the first actuating means
may then be used to unleash an animal remotely.
[0030] Preferably, the attachment means is connected to the elongate member at a swivel
joint arranged to allow rotation of the attachment means about the long axis of the
elongate flexible member. This long axis is the axis along the length of the elongate
flexible member when it is fully straightened under tension. The swivel joint prevents
twisting and tangling of the lead. Preferably, the swivel joint is a universal joint.
By "universal joint" it is meant that the joint between the attachment means and the
elongate flexible member is arranged to permit substantially unencumbered movement
of the attachment means relative to the lead, about the universal joint, over a solid
angle of at least 2 x Pi steradians. One suitable arrangement for a swivel joint or
universal joint is a ball and socket joint, where the distal end of the lead is attached
to a socket holding a ball able to rotate therein, the ball attached to the hooked
body by a connection arm. The socket may be shaped to hold the ball whilst permitting
substantial movement of the arm relative to the socket and also permitting rotation
about the long axis of the arm. In another suitable arrangement, a swivel joint may
be located between a handle at the proximal end of the lead and the elongate member,
rather than, or in addition to, a swivel joint at between the attachment means and
the elongate member of the lead.
[0031] A specific first embodiment of the present invention will now be described, by way
of example only, with reference to the accompanying drawings in which:
Figure 1 shows a schematic perspective view of a first embodiment of the distal part
of a lead according to the first aspect of the invention, with the release frame 5
in the closed configuration, the locking arrangement in the locked configuration and
the gate 7 in the first position.
Figure 2 shows a side elevation view of the attachment means of the first embodiment,
with the locking pin 14 disengaged so that the locking arrangement is in the unlocked
configuration and the release frame 5 is located part-way between closed and open
configurations.
Figure 3 shows a side elevation view of the hooked clip of the first embodiment, with
the locking pin 14 disengaged and so that the locking arrangement is in the unlocked
configuration and the release frame is in the open configuration.
[0032] In Figure 1, the distal end of a lead according to the first embodiment of the invention
is shown. In this embodiment the elongate flexible elongate flexible member is a strap
1 attached by a connector 2 through a swivel joint 3 to a hooked body 4. The hooked
body 4 forms an aperture 20 surrounded by the hooked body and first terminal 15 and
second terminal 16. A release frame 5 is pivotally mounted to the hooked body 4 by
axle 6. A gate 7 has its proximal end pivotally mounted to the release frame 5 at
a second axle 8: The gate has a free distal end 9. The gate 7 is biased towards its
first position, the position shown in the Figures by a spring (not shown) biasing
the gate 7 towards this first position with a stop (not shown) preventing it from
moving past this first position relative to release frame 5. The gate 7 may be urged
against the biasing of the spring to move it pivotally about axle 8 so that distal
end 9 may be moved towards the body of release frame 5. Holes 11, 12 are provided
in release frame 5 and hooked body 4 respectively, and when the release frame 5 is
in the closed configuration, as shown in Figure 1, a locking pin 14 is arranged to
pass through holes 11, 12 in order to hold the release frame 5 and hooked body 4 locked
together in the closed configuration.
[0033] A lanyard 13 passes through a hole in the release frame 5 and may be gripped and
pulled by a handler in order to move the release frame 5 from its closed configuration,
as shown in Figure 1 to its open configuration, as shown in Figure 3, once the pin
14 has been removed to unlock the arrangement.
[0034] The release frame 5 has a decoupling member 10 arranged to sweep across the aperture
20 as the release frame 5 is moved from the closed to the open configuration by rotation
about axle 6.
[0035] A biasing means (not shown) urges the release frame 5 towards the closed configuration
as shown in Figure 1. Hence, if the release frame as shown in Figure 3 were hot held
in place, for instance by the handler, the release frame 5 would be returned to the
arrangement shown in Figure 1 by rotation about axle 6 because of the action of the
biasing means (not shown).
[0036] In order to attach the hooked body 4 to a fastening loop of a collar or a harness,
the attachments means is employed in the arrangement shown in Figure 1 either with
or without the locking pin 14 present holding the release frame 5 in the closed configuration.
In the description that follows, it is assumed that the locking pin 14 is in place
holding the release frame 5 locked in its closed configuration relative to hooked
body 4. In order to engage the hooked body 4 with a fastening loop, the gate 7 is
pressed with its distal end 9 against the rim of the fastening loop. This urges the
distal end of the gate 7 inwards into the aperture 20 against the biasing means (not
shown) and allowing the gate 7 to pivot around axle 8. The gap between second terminal
16 and first terminal 15 is thus opened allowing the fastening loop to enter into
aperture 20 past second terminal 16. Once the fastening loop has passed the distal
end 9 of gate 7 through the gap between the distal end 9 and second terminal 16, the
biasing means (not shown) causes the gate 7 to spring back into its first position,
closing the gap and holding the rim of the fastening loop interlocked with the hooked
body 4 inside of the aperture 20. Once the rim of the fastening loop is interlocked
inside aperture 20 in this manner, it cannot be inadvertently released as the gate
7 is configured to only move inwards towards the release frame 5 and hooked body 4,
towards its second position, and not to move outwards past the first position. In
order to permit the fastening loop to be removed from aperture 20, it would be necessary
to manually press the distal end 9 of gate 7 into the aperture 20 in order to form
a gap to allow the fastening loop to be removed. This would be the case when the attachment
means is in the locked configuration with the locking pin 14 passing through holes
11 and 12 holding the release frame 5 in its closed configuration relative to the
hooked body 4.
[0037] Figures 2 and 3 show how the apparatus of the invention may be used to disengage
a fastening loop from hooked body 4 without the need to manipulate gate 7, even whilst
the lead is under tension. Figure 2 shows the release frame 5 part-way between its
closed and open configurations and in Figure 3 the release frame is shown in the open
configuration. As the release frame 5 moves from the closed to the open configuration,
the gate 7, rotatably attached to the frame at axle 8 and biased towards its first
position, is retracted from the gap between the first terminal 15 and second terminal
16. This opens the aperture 20 so that any fastening loop may, in theory, be pulled
out of the aperture 20 and removed from the hooked body 4. However, when the lead
is under tension, any fastening loop will still be held within the hook formed by
second terminal 16 and hooked body 4. This is clear from Figure 2. However, as the
release frame 5 is moved from a partially open configuration to the open configuration
as shown in Figure 3, the decoupling member 10 which forms part of the release frame
5 sweeps across the distal part of aperture 20 and will urge the rim of any fastening
loop within aperture 20 over the end of second terminal 16 to allow the fastening
loop to disengage from aperture 20 and hooked body 4, even when the lead is under
tension.
[0038] Once the attachment means has been disengaged from the animal collar or harness in
the manner described above, the release frame 5 can be allowed to rotate about axle
6 to the closed position (as shown in Figure 1) and is urged to do, once released,
by the biasing means arranged to urge rotation of the release frame 5 from its open
position towards the closed position about axle 6. Once the release frame 5 has returned
to the closed position, the handler may replace locking pin 14 into aligned holed
11, 12 to lock the release frame 5 in the closed configuration relative to hooked
body 4 with gate 7 once again in its first position closing the gap between first
terminal 15 and second terminal 16.
[0039] It will be appreciated that numerous modifications to the above described embodiment
may be made without departing from the scope of the invention as defined in the appended
claims. For example, the locking arrangement may employ a bolt and wing-nut arrangement,
rather than a pin, passing through holes in the hooked body and release frame to provide
the locked configuration. For instance, instead of the release frame being actuated
by pulling on lanyard 13, this may be connected, through a pulley or lever arrangement,
to a first trigger at the proximal end of the lead, whereby the release frame may
be moved into the open position to unleash the animal by pulling the first trigger.
[0040] The described and illustrated embodiments are to be considered as illustrative and
not restrictive in character, it being understood that only the preferred embodiments
have been shown and described and that all changes and modifications that come within
the scope of the inventions as defined in the claims are desired to be protected.
It should be understood that while the use of words such as "preferable", "preferably",
"preferred" or "more preferred" in the description suggest that a feature so described
may be desirable, it may nevertheless not be necessary and embodiments lacking such
a feature may be contemplated as within the scope of the invention as defined in the
appended claims. In relation to the claims, it is intended that when words such as
"a," "an," "at least one," or "at least one portion" are used to preface a feature
there is no intention to limit the claim to only one such feature unless specifically
stated to the contrary in the claim. When the language "at least a portion" and/or
